A second K-9 officer is hitting the streets for the Rock County Sheriff's Office. At one point years ago, the Rock County Sheriff's Office had three K-9 units, but budget cutbacks eliminated the program. Since 2010 the agency has been rebuilding. Now, Captain Jude Maurer says the sheriff's office has two K-9's again. Maurer says it's good to have this type of resource back. He says the dogs are invaluable in drug detection and missing person searches. The two teams include Deputy Shawn Nolan and Dex, along with Deputy Nathan DeBoer and Sasha. Sasha is the newest K-9 to join. Shes a 17-month-old German Shepherd mix from Slovakia.
